"We'll see how he feels tomorrow," Williams said. "I would imagine some general body soreness tomorrow after being off a little while and getting back on the slope, but he had no pain throwing. That's a good sign."

Strasburg is in the middle of his second stint on the DL this year. His first came after a tough start to the season, but before this current trip, he showed much improvement, going 2-0 with two earned runs allowed in 15 2/3 innings.

His next step has yet to be determined.

"[It] depends on how he feels," Williams said. "It was a light bullpen today for the first one. I wouldn't necessarily expect that we'd throw him right into a game. We'll see where he is tomorrow, though, and have a better idea."

Strasburg, the No. 1 overall pick of the 2009 Draft, is 5-5 with a 5.16 ERA in 2015.
